The thing which I understand from your website's SEO is:

1. You used too much same anchor text "taxi noi bai" in your backlinks. Create backlinks naturally
2. You did only a small amount of content marketing. Produce content in bulk and then submit to different blogs, guest blogs, article submission directories, etc.
